How to fix error E20 on Bosch dishwasher?

The good news is that this error code may have solutions that you could try yourself, before calling any technical support for help. To fix the E20 error code on your Bosch dishwasher, you can follow these steps:

1. Restart the dishwasher to reset the sensors: Sometimes, a simple restart of your dishwasher can be the solution to the problem. To do this, unplug your dishwasher from the electrical outlet for a few minutes and then reconnect it. Now turn it on and try running a wash cycle to see if the error has disappeared.
2. Check the circulation pump and electrical wiring: To access the pump, you'll need to remove the lower panel of the dishwasher. Check if the pump rotates freely and if there are any objects stuck in it. Also, inspect the wiring to ensure it is properly connected and shows no signs of damage, corrosion, or burning. If the pump is broken, you'll need to replace it with a new one, and if the wiring is in poor condition, you'll also need to repair or replace it.
3. Clean your dishwasher's filter: The filter is located at the bottom inside the dishwasher. Remove it and clean it with warm water and a soft-bristle brush. There's no need to apply much pressure when cleaning this filter; do it gently to avoid damage, and remove any food or dirt residues it may contain. Put it back in place, ensuring it fits well, and there's no need to tighten it too much.
4. Unclog the drainage tube and/or drain of your dishwasher: Check if this tube is bent or has any obstructions. If so, straighten it, adjust it, or remove whatever is blocking it. You can also use a wire to clean the inside of the tube and blow it forcefully from one of its ends.
5. Check the water outlet valve in your dishwasher: The valve is located at the back of the dishwasher, near the drainage tube. It is responsible for opening and closing to allow or prevent the passage of water. Check if the valve is functioning correctly and if there is any object preventing it from opening or closing. If the valve is damaged, bent, or in poor condition, you'll need to replace it with a new one.
6. Clean the water level sensor of your dishwasher: The sensor is located at the bottom of the dishwasher, next to the filter. It measures the amount of water inside the appliance. Check if the sensor is dirty or has any food residue stuck to it. If so, clean it with a damp cloth and dry it thoroughly.
7. Repeat all the previous steps if the problem persists: You can perform a second check of everything described above in case the problem persists. If after all the checks and cleanings, the error continues to appear, there may be another faulty component that requires a more complex repair.
8.
